# (i) compared to older gcc 3.x one can observe >2x improvement on
|
|
# most platforms;
|
|
# (ii) as it can be seen, SSE2 performance is too low on legacy
|
|
# processors; NxSSE2 results are naturally better, but not
|
|
# impressively better than IALU ones, which is why you won't
|
|
# find SSE2 code below;
|
|
# (iii) this is not optimal result for Atom because of MSROM
|
|
# limitations, SSE2 can do better, but gain is considered too
|
|
# low to justify the [maintenance] effort;
|
|
# (iv) Bulldozer actually executes 4xXOP code path that delivers 2.20;
